WILLIAM GREGERSEN, OF ST. ANDREWS PA RISH, SOUTH CAROLINA.

SURF OR WAVE MOT OR.

Application filed June 25. 1918.

To all whom it may concern:

Be it known that I, \Vnmrnr Gnnoi-insnu, a citizen of the United States, residing at St. Andrews Parish, in the county of Charleston and State of South Carolina, have invented new and useful Improvement; in Surf or \Vave Motors, of which the following is a specification.

The invention relates to motors and more particularly to the class of surf or wave motors.

The primary object of this invention is the provision of a motor of this character wherein the incoming tide of the waves in a body of water will exert force which will operate the motor so that the power from the Wave or sur can be utilized for the driving of machinery or the like.

Another object of the invention is the revision of a wave motor in which the ody thereof is in the form of a boat pivotally supported so that it'will rock and thereby operate the mechanism which Wlll in turn rotate a shaft so that the rotary motion thereof can be transferred to machinery or the like for the of the same from the force of theiwaves or surf in abody of water. i

A further object of the invention is the provision of a wave motor which is simple iii construction, durable, may be easily and conveniently operated and one which is thoroughly reliable and efficient in the performing of its functions, aswell as being inexensive to manufacture.

With these and other objects in view the invention consists in-the construction, com bination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereunto appended.

In the drawings:

Figure 1 is a side elevation of a motor constructed in accordance with the invention, the same being-shown tilted in one position by the incoming tide of a body of water.

Fig. 2 is a similar view showing the body of the motor in a reverse position on the ebb of the tide.

Fig. 3 is an end elevation.

Fig. 4 is at vertical transverse sertioual view.

Fig. 5 is a view of the ratchet wheel and operating lever.

Similar reference characters indicate cor- Specification of Letters Patent.

respondin parts throughout the several Views in t 1e drawings.

Referring to the drawings by numerals. the surf or wave motor comprises a pair of spaced vertical columns or posts 5 which are anchored in the bed of a body of water near the shore thereof, and arranged between these columns or posts is a flat boat-shaped body (3 having inwardly sloping ends 7 the body being supported for rocking movements upon a shaft 8, which is loosely passed through the body medially thereof, and also is journaled in bearings 9 suit'ab y mounted upon the columns or osts 5, the said body 6 bei laced a suite le distance above the bed of he bod of water and is so positioned as to receive t e force and impact of the in coming and ebbing tide or surf, whereby the body rocks upon the shaft for rotatingthe same in a manner resently described.

Fixed to and rising from the boat body 6 centrally thereof are upri hts 10 which are arrangedin spaced relation to each other and in pairs at'opposite sides of thebody. Connected 'to the ends of the boat body 6 and to the u rights are upwardly converging riggingb orming braces 11 the said uprights also eing connected with cross braces 12 so as to assure strength and rigidity thereto.

Adjustably fixed in the uprights 19 in any suitable anner are perforated cars 13 which extend outwardly and laterally from the Side of the boat body 6 and which are provided with openin s 14 through which are-passed operating evers 15, each being formed with a fork 16 at its inner end which loosely engages the shaft 8 which has fixed thereto ratchet wheels 17, the same being open as hereinafter specified.

Carried in the forks 16 are spring held pivoted pawls 18 which are adapted to ride upon the toppf the ratchet wheels 17 for engagement therewith wherehy on the rocking of the boat body 6 the levers 15 will operate for the intermittent releasing and engaging of the pawls 18 from and with the teeth of the ratchet wheels 17 for imparting rotation to the shaft 8 for the driving there of. The levers l5 h ye fired theret; stops 1!) which are adapted to be engaged by the guide ways 13 so as to teady the bout body G when passive or when operated thereon by the force of the waives or thr surl' on the in mining or e ing of the tide.

The shaft 8 has fixed thereto at oppo ite loosely journale sides of the boat body 6 fly wheels 20 which assure a uniform momentum during the drivin of the shaft when the motor is in operation. In the operation of the motor the incoming tide exerts an impact force against one end of the boat body 6 causing it to rock to the position shown in Fig. 1. The pawl 18 being engaged with the ratchet wheel 17 will effect a turning of the shaft 8 thereby turning the same in one direction. Now on the ebbing of the tide the boat body 6 will be rocked in a reverse direction or to the position shown in Fig. 2 of the drawing and durin this movement of the said body the pawls T8 will ride over the ratchet wheels 17 so as not to impede or interfere with the rotation of the shaft 8.

From the foregoing it is thought that the construction and manner of operation of the device will be clearly understood.

What is claimed is:

1. A motorof the class described comprising supports, a. rotatable shaft journaled upon saidsupports, a rocking body mounted upon the shaft, uprights rising from the said body, ratclietfwheels fixed to the shaf't at opposite sides of the body, 0 erating levers slidably engagin the upriglits, said shaft in i said operating lever, and ivoted spring held pawls mounted. on the evers and enga ing said ratchet for turning the same on t e rocking of the body whereby motion will be imparted to the shaft.

prising supports, a rotatable shaftfjournaled u on said supglortaa rocking body mounte upon the s aft, uprights rising from the saidbody, ratchet wheels fi'xedto the shaft at opposite sides of the body, operating levers slidably engaging the uprights, said shaft loosely journaled in said levers, pivoted spring held pawls mounted on the levers and engaging said ratchet wheels for tlirnin the same on the rockin of the body where 24' motion will be impartec l to the shaft, and y wheels carried by the same shaft.

3. A motor of the class described comprising supports, a rotatable shaft journaled upon said supports, a rocking body mounted upon -the shaft, uprights rising from the said body, ratchet wheels fixed to the shaft at opposite sides of the body, operating levers slidably engagin the uprights, said shaft loosely journa ed in said levers, pivoted spring held pawls mounted 2. A motor of the classjdescribedcom on the levers and engaging said ratchet for turning the same on the rocking of the body whereby motion will be imparted to the shaft, fly wheels carried by the same shaft, and guide ways mounted upon the uprights and engaging the operating levers.

4. A motor of the class described comprising supports, a rotatable shaft journaled upon said supports, a rocking body mounted upon the shaft, uprights rising from the said body, ratchet wheels fixed to the shaft at opposite sides of the body, operating levers slidably engaging with the uprights, said shaft loosely ournaled in said levers, pivoted spring held pawls mounted on the levers and engaging said ratchet for turning the same on the rocking of the body whereby motion will be imparted to the shaft, fly wheels carried by the same shaft, guide ways mounted upon the uprights and engaging the operating levers, andstops upon the operating levers and cooperating with the guide ways. v

5. In a Wave'motor, a rockable body, uprights rising from said body, operating levers slidably engaging said uprights, a Shaft loosely journaled in said levers, andmeans connecting said shaftsand levers to rotate the shaft upon movement of the levers by the rocking of said body. y

6. In a wave motor, a shaft, a rockable body, uprights rising from said body, op

crating levers slidably engaging said] up-l rights and means connec ting said shaft and levers to rotate the shaft 11 on movement of the lovers by rocking of said body.

7. In a Wave motor, a. shaft, a rockab'le body, uprights rising fromsaid body, operating levers slidably engaging said uprights, ratchets carried by said shaft, and pawls carried by said levers for engaging said ratchets to rotate the shaft upon movement of the levers by the rocking of said body. I

8. In a wave motor, a shaft, a body rockably mounted upon said shaft, o erating'levers slidably engaging said bo y, ratoh'ets carried by said shaft, and pawls carried by said levers and engaging said ratchts to rotate said shaft by the rocking of said body.

In testimony whereof I affix my signature in presence of two witnesses.
